Quick Energy Check: A Simple Breathing Technique Takes the Internet by Storm

A simple breathing technique, known as "svistelok," is gaining popularity as a quick way to assess personal energy levels. Developed by fitness expert Nadezhda Fridman, the method involves a simple exhale with a whistling sound. "A strong, clear whistle indicates good energy levels," Fridman explains in her video tutorial. "But if it's weak or barely there, it's time to get moving!" Fridman's video, which has garnered significant views in a short time, has sparked interest in this easily accessible self-assessment tool. While further research is needed to fully validate the technique, its simplicity and potential benefits make it an intriguing addition to personal wellness routines. The technique is part of a larger exercise program offered by Fridman, which includes a free trial period.
